Significant enhancement of magneto-optical effect in one-dimensional photonic crystals with a magnetized epsilon-near-zero defect

Significant enhancement of magneto-optical effect in one-dimensional photonic crystals with a magnetized epsilon-near-zero defect

Optical nonreciprocal transmission possesses a broad range of applications such as optical isolation, all-optical signal processing, and integrated photonic circuits. The main underlying mechanism is that a static magnetic field can break the time-reversal symmetry in the presence of magneto-optical materials. However, the typical devices usually need a large size …
